Non-wetting of condensation-induced droplets on smooth monolayer suspended graphene with contact angle approaching 180 degrees

Abstract Superhydrophobicity is usually achieved by a combination of chemical hydrophobicity and surface topography due to an inability attain complete non-wetting on the smooth existing materials. Here, we experimentally report high condensation-induced droplets with contact angles approaching 180° suspended monolayer graphene. Such highly are found graphene open water vapour saturated environment both sides. Simultaneous observations condensing multilayer supported demonstrates that this behaviour may be unique These results anticipate interactions between liquid molecules across isolated from bulk substrate induce beyond possible hydrophobic or atomically flat surfaces.
